Eshabhu laseJinbin, kwenziwe izinto ezintathu ezenziwe ngokwezifisoama-goggle valvengoba amakhasimende asezoqedwa. Abasebenzi benza ukucubungula kokugcina kuzo. Lezi zingumlandeliivalvu eyimpumputhe enomumosenosayizi we-DN1450, ifakwe idivayisi kagesi. Sebehlolwe kakhulu ngengcindezi kanye nokuhlolwa kokuvula nokuvala futhi balinde ukupakishwa nokuthunyelwa.

I-valve yepuleti eliyimpumputhe yomkhakha omkhulu enobubanzi obuyi-DN1000 nangaphezulu iyimishini ebalulekile eyenzelwe ukuhlangabezana nezidingo zokuhlukanisa zezinhlelo zamapayipi amakhulu kakhulu.

Ngokuphathelene nezinzuzo, eyokuqala ukusebenza kwayo okuhle kakhulu kokuvala. Lolu hlobo lwe-valve lusebenzisa kakhulu isakhiwo sokuvala esikabili se-"elastic seal + metal hard seal", esingase sifinyelele ukuvuza okungenalutho ngisho nangaphansi kobubanzi obukhulu be-DN1000 nangaphezulu. Lufaneleka kakhulu ezimweni ezinezidingo eziqinile zokuvala njengegesi kanye nemidiya enobuthi, okugwema inkinga yamandla angalingani ebusweni bokuvala okubangelwa ububanzi obukhulu.

Okwesibili, isebenza kahle kakhulu futhi kulula ukuyisebenzisa. Isakhiwo esifana nefeni sincane kakhulu kunepuleti eliyimpumputhe lendabuko, futhi isisindo saso singama-60% kuphela kunelevalvu yesango enobubanzi obufanayo. Ingahlanganiswa namadivayisi kagesi nawomoya ukuze kufezwe ukuvulwa nokuvalwa okukude, kuxazululwe inkinga yokusebenza kanzima ngesandla kwamavalvu amakhulu. Isikhathi sokuvula nokuvala sevalvu eyodwa sivame ukulawulwa zingakapheli imizuzwana engama-30, okuthuthukisa kakhulu ukusebenza kahle kokusebenza.

Ngaphezu kwalokho, inokweqisa okukhulu kokuphepha, ifakwe amadivayisi okukhiya ngomshini kanye nezinkinobho ezikhawulelwe ukuvimbela ukusebenza kabi. Umzimba wevalvu oyimpumputhe wenziwe ngensimbi eqinile noma amapuleti ensimbi ahlanganisiwe, angamelana nokucindezela okuphezulu (ngokuvamile kufika ku-1.6MPa) kanye nokushayisana, futhi afanelekela izimo zokusebenza eziyinkimbinkimbi. Ngaphezu kwalokho, izindleko zokulungisa ziphansi. Izingxenye zokuvala zingahlukaniswa futhi zithathelwe indawo ngokwahlukana ngaphandle kwesidingo sokuhlakaza lonke ipayipi. Ifaneleka kakhulu ezimweni zokukhiqiza eziqhubekayo ezinhlelweni zamapayipi amakhulu lapho "ukuvala kusho ukulahlekelwa".

Izimo zokusetshenziswa zigxile kakhulu ezindaweni ezibalulekile ezidinga ukwahlukaniswa okukhulu: Kubunjiniyela begesi kamasipala, ivame ukusetshenziswa emipayipini emikhulu yamanethiwekhi egesi yemvelo yasemadolobheni anobubanzi obusukela ku-DN1200 kuya ku-DN2000, ukuze kufezwe ukwahlukaniswa okuphephile ngesikhathi sokulungiswa kwamapayipi kanye nokuxhumeka kwegatsha, kugwenywe ukucima okukhulu kwegesi. Emayunithi okuhlanza umoya kanye ne-vacuum kanye namayunithi okuqhekeka kwe-catalytic embonini ye-petrochemical, imipayipi emikhulu yokuthutha uwoyela ongahluziwe kanye nemikhiqizo kawoyela ocwengekile enobubanzi obungaphezu kwe-DN1000 idinga ukushintsha izinqubo njalo noma ukuhlukanisa imishini.

Izici zazo zokuvula nokuvala okusheshayo zinganciphisa isikhathi sokuphazamiseka kokukhiqiza. Ezinhlelweni zokususa i-sulfurization/denitrification ezimanzi embonini yamandla, ifanelekela amapayipi amakhulu egesi yomoya anobubanzi obuyi-DN1500 noma ngaphezulu, futhi ingahlukanisa igesi yomoya enokushisa okuphezulu (enokumelana nokushisa okufika ku-300℃) ngesikhathi sokulungiswa kwe-reactor. Uhlelo lokususa uthuli olomile lwegesi yomlilo embonini yensimbi ludinga ukuthi amapayipi okudlulisa igesi anobubanzi obuyi-DN1200 nangaphezulu amelane nokuguguleka kwemidiya equkethe uthuli. Isakhiwo sayo sokuvala insimbi eqinile singasebenza ngokuzinzile isikhathi eside.

Njengomkhiqizi oneminyaka engu-20 ubudala wamavalvu ensimbi (i-Electric Blind Valve), i-Jinbin Valves inikeza amakhasimende izixazululo zokulawula uketshezi ezisezingeni eliphezulu kanye nensizakalo yomuntu nomuntu. Uma unemibuzo ehlobene, sicela usithinte ngezansi futhi uzothola impendulo zingakapheli amahora angu-24!
